This study was designed to examine the degree of success of two current programs of the International Federation of Library Associations--Universal Availability of Publications (UAP) and Universal Bibliographic Control (UBC)--as they are seen from the point of view of one library. The data analyzed were culled from 237 interlibrary loan requests received from libraries outside the United States by the Physical Sciences and Technology Libraries' Interlibrary Services Section of the University of California at Los Angeles. The analyses considered various aspects of the requests and the borrowing institutions, together with the known responses of the Interlibrary Services Section as a lender. Control of the report literature was found to be unsatisfactory because libraries tend not to state whether they have verified titles in bibliographic or union catalogs, nor do they state if they make use of their national centers. Clarification of responses in the area of "incomplete" transactions and use of national centers to verify citations was sought through a postcard survey of Canadian libraries, which constituted the largest group of users. More investigation is needed in several areas of response to national and international interlibrary loans by U.S. libraries. Appendixes include notes on the variables and values; results of the questionnaire to Canadian libraries; the cover letter to Canadian libraries; a test of the questionnaire; and 75 tables.
